Y., assignox to General Beauty Products, Inc., New York, N. Y., va corporation of New York Application June 24, 1955, Serial No. 517,678 1 Claim. (Cl. 259-.-107) This invention relates to powder mixing devices and more particularly to an apparatus for mixing or blending face powders of various shades so as to derive a desired blend. As a general matter, such devices are utilized to produce a personal blend or mixture which conforms to an individuals requirements.

Pursuant to the instant invention, a device is disclosed which quickly and eticiently mixes a plurality of powder batches so as to achieve a line and accurate blending thereof without objectionable streaks. The device utilizes a plurality of beaters or mixers and these are so arranged as to eiect uniform blending over a relatively wide area while, in effect, sifting the powder through the beaters themselves which are of substantially loop form. The device is further such as to avoid, as far as possible, such undue vibration of the entire structure as would tend to spill powder or disperse a spray thereof from the device when the device is in operation.

The invention will be further understood from the following description and drawings in which:

Figure 1 is a front elevational view of the improved powder blender;

Figure 2 is an enlarged cross-sectional view as taken along the line 2 2 of Figure 1;

Figure 3 is a cross-sectional view as taken along the line 3 3 of Figure 2;

Figure 4 is a cross-sectional view as taken along the line 4 4 of Figure 2;

Figure 5 is a cross-sectional view as taken along the line 5 5 of Figure 2;

Figure 6 is a reduced cross-sectional view as taken along the line 6-6 of Figure 2;

Figure 7 is a developed view of the beaters per se as taken along the line 7 7 of Figure 6; and

Figure 8 is a schematic view of the power circuit.

The device takes the form of a body 10 which houses the powder as well as the power drive equipment. Body 10 includes a powder receptacle 11 having a cover 12 which ts snugly over the mouth of the receptacle so as to close it against the likelihood of powder sprays while the device is in operation.

The body 10 is preferably but not necessarily, fabricated of plastic material such as cellulose acetate or the like whereby the cover 12 may have a resilient snap-vv iit over the receptacle mouth. However, any conventional cap means may be employed.

The beating and blending mechanism includes the motor shaft 13 to which is secured as by bolt 14, the horizontal disk 15. A number of beaters, herein illustrated as iive in number, are radially disposed on the disk 15 and are uniformly angularly spaced thereabout so that in the illustrated instance, the beaters are 72 apart. Each beater 16 comprises a single length of wire which is doubled upon itself but wherein the center portion is formed as a loop. The beaters comprise an upper horizontal portion 17 formed of the adjacent or coincident wire ends and welded or otherwise secured to disk 15..

ice

The depending portion 18 also comprise opposite wire sections maintained adjacent each other. In the loop section 19, the wires gradually diverge so as to form the loop.

An important element of the beater arrangement is the plane of the several loops. Considering, for example, beater 16a, the loop thereof is in a horizontal plane.

Loops 1617 to 16e deviate progressively from the horizontal plane, the loop 16e being in a vertical plane. Considering the loops as graduating from the horizontal to the vertical state, the center loop 16c is about 45, loop `16b being about 221/2" and loop 16d being about 671/2?. The eiect of thus variably tilting vand equi-angularly spacing the beaters is to achieve an expeditious and iine blending of the powder mix as will hereinafter be described. Y

The power drive for the beaters is disposed in the hollow base 20 which is integral with the receptacle portion 11, a transverse, circular partition 21 dividing them. The bottom of hollow base 20 is enclosed by a bottom cover 22.

The base is formed with an internal flange 23 to which is secured a circular panel 24. Panel 24 is formed with a plurality of openings designed to accommodate batteries and a motor 25 of which 13 is the shaft.

The outward openings 26 are shown as three in number and thereby accommodate three batteries which may advantageously be of the usual 11/2 volt variety. In the form shown, the three batteries 27 are arranged in series so that the total voltage to the motor is 41/2 volts. A convenient method of mounting the batteries is illustrated in Figure 4 where rivets 28 are secured to the panel 24 which is of insulating material while spring clips 29 effect electrical contact with the battery terminals. Wires 30 connect the succession of rivets in a series arrangement. Such a battery arrangement makes it very easy to replace used batteries and the whole arrangement serves to stabilize the device mechanically as will be hereinafter noted.

In order to complete a circuit, a button switch 31 mounted on a spring arm 32 is provided, said spring arm electing electrical contact with contacts 33 and 34 one of which goes to the motor and the other to the batteries as illustrated in Figure 8. Of course, no claim is made for the circuit itself, this circuit being purely conventional and any conventional system being usable. However, the disposition of the motor 24 and angularly arranged batteries 27 is such as to effect good balance of the device by uniformly disposing the relatively heavy batteries 27 around the periphery of the base and wherein the motor is disposed between them so as to augment such balance and jointly lower the center of gravity of the device as a whole.

The device is operated as follows:

In general, the user will have available a number of different powder batches, each of varying shades. She will estimate the quantities of various shades required to give a particular desired blend. This is, of course, conventional. After having deposited the required powv der materials in the receptacle 11, the operator will press beaters with practically no area served by the beaters leftY 0f course, the loops 19 may" free of the sifting action. be larger than shown in order to increase suh area, the size shown 'being only illustrative.
